Smoked Mozzarella Bread Pudding

This rustic Smoked Mozzarella Bread Pudding is made with tangy sourdough and chock full of stretchy smoked mozzarella cheese. Hearty enough for a vegetarian main dish, or serve it as a side dish at your next holiday dinner.

Smoked Mozzarella Bread Pudding

Bread pudding recipes are so easy to make and satisfying to eat. I have quite a few sweet ones in my repertoire, but this savory one is really special. It’s quite good on its own for a quick lunch with a side salad, but it really shines as a dinner party side dish. Thanksgiving is next week, and if you find the idea of making scratch-made dressing daunting, then I suggest this dish – not as a replacement – but as a worthy alternative.

Leek love.

Leeks are the unsung hero of this dish. The comically large oniony stalks break down easily and impart mild onion flavor. But you’ll need to clean them thoroughly! Their sheaths can hold some of the sandy soil they are grown in. Split one down the center with a large knife and clean each layer individually. Then give them the ol’ chop-chop.

Smoked Mozzarella can be found at nearly any cheese counter at well-stocked grocery stores. Go for the block variety, and not the pre-shredded stuff in the bags. Because those shreds have stabilizers in them to prevent them melting during shipping. You’ll need 8 oz. of smoked mozzarella, grate half of it. Pull apart the remaining cheese with your fingers to create 1/2-inch pieces. Set the grated portion aside – it goes on top right before baking.

Cut a loaf of sourdough to 1-inch cubes and toss in a large bowl. Mix up the custard with the smoked mozzarella bits and lots of eggs. (Better add an extra dozen to the grocery list!) The custard has a lovely buttermilk tang to match and enhance the sourdough flavor.

You could make this in a single 10-inch cast iron skillet, or even a 13×9 inch casserole dish. But I decided to use these little individual 14 oz. cast iron skillets. (You could also use 14 oz. ramekins.) I had purchased them when my husband wanted individual skillet cookies for his birthday party a few years ago. They were perfect for this savory bread pudding, and the serving size is generous.

Spoon the bread mixture into the mini skillets, and place them on a large baking sheet so they’re easy to transfer to the oven. They don’t take very long to bake in individual portions. Only 20-ish minutes. If you’re cooking this as one big dish, you’re looking at about 40-45 minutes bake time.

Each little skillet holds layers of sourdough, pockets of smoked mozzarella, and mild sautéed leek. The buttermilk custard adds richness and another layer of tangy flavor. I can’t wait for you to try it!

This rustic, tangy sourdough bread pudding is a meal unto itself. It’s also a lovely side for a dinner party or special occasion dinner. This dish can be cooked as one large bread pudding in a 10-inch cast iron skillet or a 13×9 inch baking dish. Increase the bake time to 40-45 minutes, or until well set in the center. See the recipe notes for variations with other ingredients.

Servings 6


  • 14 oz. mini cast iron skillets (6)


  • 2 cups chopped leek about 1/2 of a large leek
  • 2 tablespoons salted butter
  • 16 oz. loaf sourdough bread fluffy style, not dense/crusty
  • 8 oz. block smoked mozzarella cheese
  • 2 1/2 cups buttermilk
  • 5 egg yolks
  • 2 whole eggs
  • 1 1/2 cups heavy cream
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • Olive oil for greasing cast iron skillets
  • Chopped parsley for garnish optional


  • Sauté sliced leek in butter in a skillet over medium heat until tender and slightly translucent. Set aside to cool, 10 minutes.
  • Cube the sourdough loaf and place it in an extra-large mixing bowl. Set aside.
  • Grate half of the mozzarella cheese; cover and set aside.
  • Pull the remaining cheese apart with your fingers to 1/2-inch pieces (or cube the cheese with a sharp knife).
  • In a separate large mixing bowl, whisk together the buttermilk, egg yolks, whole eggs, and heavy cream. Stir in the cooled leeks, 1/2 inch cheese pieces, salt, and pepper. Pour the mixture over the cubed bread and stir well until all the bread cubes are coated. Mix well and press the bread down into the liquid so everything gets saturated. If the mixture seems dry, add an extra splash of buttermilk. Cover and let stand 20 minutes.
  • Preheat the oven to 375°F.
  • Brush mini cast iron skillets with olive oil. Spoon the bread pudding evenly into each skillet. Sprinkle each skillet with the reserved grated mozzarella cheese. Bake for 20-25 minutes or until a knife inserted near the centers of the puddings comes out clean, or with a little stretchy cheese attached.
  • Broil 2-3 minutes to brown the tops. Let cool slightly before serving. Garnish with chopped parsley, if using.


What to expect:
This rustic bread pudding is deliciously rich and tangy with buttermilk custard and sourdough bread. It’s hearty enough to be a meal on its own, but it’s excellent as a side for roasts and fish. It feels special served in individual cast iron skillets at special occasion dinners. See blog posts for links to the skillets.
Bake as one big dish of bread pudding.
Coat a 10 inch cast iron skillet with olive oil, or spray a 13×9 casserole dish with cooking spray. Place all of the prepared bread pudding mixture into the dish and bake for 40-45 minutes, or until the center is well set. Broil for 2 minutes to brown the top.
Add this!
Sauté one cup of fresh wild mushrooms with the leeks. This adds another layer of autumn flavor.
Add chopped sundried tomatoes for another variation. Top each bread pudding with torn fresh basil.

We had this as a side with 40 clove chicken and it was delicious. I had to use ramekins because I don’t have mini cast iron pans but now I’m thinking about investing in some.

I made this recipe and it was delicious! I served it with tomato basil soup, which was a great flavor combination. This could be a go-to side dish with a lot of things!
